IPC: H01R33/46
Filed: 1933-02-24
Abstract: 408,433. Electric - lamp holders. YATES, F. W., 2, Muriel Street, and O'BRIEN, J. A., 1, Westfield Avenue, Coatham, both in Redcar, Yorkshire. Feb. 24, 1933, No. 5660. [Class 39 (ii).] In lamp holders of the bayonet joint type wherein the contact pins are rigidly secured to an insu lating-support which is disposed in the upper part of the holder casing and held against rotary or longitudinal displacement, the lower portion or sleeve which receives the lamp cap or plug being slidable longitudinally relatively to the upper part of the casing towards which it is normally pressed by an external spring, means are provided for compressing the spring to prevent longitudinal movement of the lower portion or sleeve after a lamp cap or plug has been inserted therein, thereby forming a locking-device to prevent easy removal of the lamp or plug. The upper portion b of the casing is provided with peripheral screw-threads m to receive a securing- ring j with an inturned bottom flange n which forms the lower abutment for a helical spring o surrounding the upper part of the holder sleeve g, a flange h on the latter forming the upper abutment for the spring. The insulating- body a carrying the fixed contact pins p is provided at its top edge with a flange c which is held against a seating d by the pressure of the spring o when there is no lamp within the holder. To insert a, lamp, the bottom of the sleeve g is held and the lamp-cap pins pressed within the bayonet slots t, thereby forcing the members a, b, j upwardly against the pressure of the spring, which is compressed when the lamp is in position. The lamp is secured by screwing the ring j further on to the portion b, so that the lamp cap-pins are pressed firmly into the seatings of the slots t by the rigid contact pins p.

[Class 28 (i)] Apparatus for oiling dough pieces comprises a flexible sheet 7, e.g. of felt, which is supplied with oil from a tank 10 and drip nozzles 9, and wipes over the dough pieces 6 as they are traversed beneath the sheet by a conveyer 4 which receives the pieces from a moulding- machine delivery conveyer 2 and passes them to a conveyer 3 leading to the tin filling position. The pieces are confined on the conveyer 6 by side guides 5. The sheet 7 is suspended from a vertically adjustable bracket 8, and the tank 10 is supplied with oil by a pump 12 from an oil reservoir 13, the overflow pipe 14 of the tank leading back to the reservoir 13.

Abstract: 931,614. Wrapping-machines. FR. HESSER, MASCHINENFABRIK A.G. Feb. 15, 1962 [March 7, 1961], No. 5774/62. Class 94(1). Articles a to be wrapped are delivered from stacking means 1 and conveyed between horizontal guides 2, 3 by pusher bars 6 of a pair of endless belts 4, 5 past wrapping material e, one end portion of which is folded by one of the bars 13 of conveyers 11, 12 and the other by one of the bars 16 of conveyers 14, 15, the folded end portions being sealed by heating bands 23 attached to bars 22 of conveyers 20, 21. The wrapping material e is cut into lengths by a rotating knife 9 against a fixed knife 10. The conveyers 14, 15 are driven through eccentric gearing 17, 18 so that as the bars 16 engage the end portion of the wrapper their speed is greater than that of the bars 13 of conveyers 11, 12, so that they take over conveyance of the articles a, and prevent the bars 13 from fouling the wrappers as the bars 13 rotate outwards. The speed of the bars 16 decreases before the bars 22 engage the wrappers, for the same reason. Electric current for heat-sealing is supplied through carbon brushes 24 and rails 26. The wrapper is subsequently folded and sealed along the sides of the article.

Title: Improvements in or relating to dispersive elastic wave delay lines

IPC: H03H9/72
Filed: 1967-02-08
Abstract: 1,118,275. Electromechanical delay lines. WESTERN ELECTRIC CO. Inc. 8 Feb., 1967 [8 March, 1966], No. 6029/67. Heading H3U. A dispersive elastic wave delay line comprises, Fig. 1, a bar 10 of wave propagating material having at one end 13 a transducer 14 for launching and receiving wave energy, a circulator 18 separating the input signal source 17 from the utilization load output 19. The opposite end 15 of the bar 10 has an acoustic wave absorber 16. In order to reflect back to the end 13 signal components at different frequencies at different delay times reactive discontinuities 20, 21 are arranged along the upper and lower parallel surfaces 11, 12 of the bar. These reactive discontinuities abruptly vary the transverse distance between the surfaces 11, 12 and are formed by machining, etching, or plating the surfaces. Mathematical analysis shows that maximum total reflection of a signal of wavelength # occurs when the phase delay between adjacent discontinuities is a quarter of that wavelength or an odd integral multiple thereof, and that the maximum attainable reflection factor increases monotonically with the number of contributing sections and the mismatch factor. Hence, to obtain the desired dispersion characteristic the spacing between successive discontinuities 20, 21 as measured along the surfaces 11, 12, respectively, is continuously varied. In a modification, Fig. 4, separate transducers 40, 41 are provided for launching and receiving the elastic wave; these transducers being arranged at a small angle to each other and to the discontinuities 42.

Abstract: 753,871. Automatic frequency and phase control systems. TELEFUNKEN GES., [formerly TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE]. March 2, 1954 [March 2, 1953], No. 6042/54. Class 38 (4). In a " flywheel " synchronizing system in which an oscillation generator is synchronized by a phase control voltage derived by comparing the phase of incoming synchronizing pulses with the generated oscillation the adverse effect on the synchronization of additional pulses of greater frequency and/or longer duration in the synchronizing pulse train is compensated by a control voltage, derived from and coincident in timing with the other pulses, also applied to the phase comparing circuit. In the television line scanning synchronizing system of Fig. 2 synchronizing pulses are applied to the grid of a phase comparing valve 2 and sawtooth pulses derived from a blocking oscillator circuit 5 also to the same grid through a capacitor 3, a frequency controlling voltage being derived across the cathode resistor 4 of valve 2 and applied as bias to the blocking oscillator control grid. In addition, during disturbing frame and equalizing pulses in the train, a compensating voltage derived from the flyback circuit 12, 13 during frame flyback periods is applied through capacitor 16 and resistor 17 and superimposed with suitable magnitude and shape on the control voltage existing on the capacitor 18 of the cathode circuit of the phase comparing valve 2. Other voltage shaping networks with desired time constant instead of the capacitor 16 and resistor 17, or a multivibrator in place of the blocking oscillator, may be used.

Abstract: 125,498. Wade, H., (Hopedale Manufacturing Co.). April 15, 1918. Weft, cutting.-When indication is made for weft-replenishment, the hopper arm 15 is moved forwards and a lug 50 thereon engages a lug 52 .on the arm 49 of a bell-crank lever, so that the other arm 48 moves rearwards to open the blades of the weft cutting and clamping device, which, together with the bell-crank lever, is mounted on a bracket 23 supported on the hopper bracket 13 in such a manner that it may yield if struck by an improperly boxed shuttle. The cutting and clamping device comprises a slidable cutting-blade 35 guided by a pin and slot and having a pin 43 adapted to be engaged by the arm 48 of the bellcrank lever, a fixed clamping-blade 54, and cooperating cutting and clamping blades 55 adapted to be oscillated by the engagement of the pin 43 with a slot 42 therein. When the lay beats up, the blade 35, which has been moved rearwards by the engagement of the arm 48 with the pin 43, strikes the back 45 of the shuttle box and is thereby moved forwards into the position shown, thus closing the oscillatory blades on the weft by the engagement of the pin 43 with the slot 42. When the hopper arm 15 moves again into its normal position, the lug 52 rides over the lug 50 into the position shown. Upon the completion of the cutting and clamping operations, the weft is severed at the selvedge by means of a threadcutter connected with the temple, the clamping- blades holding the severed weft end till the next weft-replenishment, when it is released to fall into a receptacle or on to the floor.
